EXTR SWR SWDTEN WDTO SLEEP IDLE BOR POR
bit 7 bit 0
bit 13 BGST: Bandgap Stable bit
1 = The bandgap has stabilized
0 = Bandgap is not stable and LVD interrupts should be disabled
bit 12 LVDEN: Low Voltage Detect Power Enable bit
1 = Enables LVD, powers up LVD circuit
0 = Disables LVD, powers down LVD circuit
bit 11-8 LVDL<3:0>: Low Voltage Detection Limit bits
1111 = Input to LVD is the LVDIN pin (1.24V threshold, nominal)
1110 = 4.6V
1101 = 4.3V
1100 = 4.1V
1011 = 3.9V
1010 = 3.7V
1001 = 3.6V
1000 = 3.4V
0111 = 3.1V
0110 = 2.9V
0101 = 2.8V (default value at Reset)
0100 = 2.6V
0011 = 2.5V
0010 = 2.3V
0001 = 2.1V
0000 = 1.9V
Note: The voltage threshold values shown here are provided for design guidance only. Refer to the
“Electrical Specifications” in the device data sheet for further details.
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
Note: See Section 8. “Reset” for a description of other bits in the RCON register.
